Wet End Waxy Amphoteric Starch Impacts Drainage, Retention and Strength, 1990 Papermakers Conference Proceedings
Robert T. McQueary--New developments in high performance amphoteric starches based on waxy maize starch have allowed papermakers to obtain higher retention, better formation and faster drainage as well as strength. These benefits enable mills to optimize their furnish variables, machine operations and paper quality. Virtually every grade of paper and paper board has been impacted with this new technology. The techniques have been applied in acid, neutral, and alkaline conditions. Examples of the benefits obtained are illustrated in numerous examples.
